Book Description
"In this thesis, three issues about the intercity travel demand on the US transportation network are addressed. The final one is the estimation of the domestic passengers' delay cost. A scheme is designed by assuming that costs incurred by flight delays relative to the original flight schedules are imposed at passengers' final destination airports. It is applied to estimate the total domestic delay cost of year 2007 and reasonable results arc obtained. The second one is the air travel demand estimation. Two route-based optimization models are proposed to estimate the travel demand based on available data. It is shown that the estimated route flow follows logit model and nested logit model, respectively. And the domestic demand of year 1995 between 486 airports within continental U.S. is estimated. The last one is the analysis of intercity travel pattern for the super large network. A efficient Pseudo-Dynamic Traffic Assignment simulation model is presented to analyze the traffic patterns of the intercity travellers as well as the related fuel consumptions and emissions. A two-stage simulation scheme is proposed to separate the intercity and non-intercity link flows. Results analysis illustrates that the method gives reasonable estimation within acceptable run-time. The model is applied to the network covering contentional U.S."--Abstract, leaf iii.

Book Description
Many current traffic management schemes are tested and implemented using traffic simulation. An Origin- Destination (OD) matrix is an ideal input for such simulations. The underlying travel demand pattern produces observed link counts. One could use these counts to reconstruct the OD matrix. An offline approach to estimate a static OD matrix over the peak period for freeway sections using these counts is proposed in this research. Almost all the offline methods use linear models to approximate the relationship between the on-ramp and off-ramp counts. Previous work indicates that the use of a traffic flow model embedded in a search routine performs better than these linear models. In this research, that approach is enhanced using a microscopic traffic simulator, AIMSUN, and a gradient-based optimization routine, MINOS, interfaced to estimate an OD matrix. The problem is highly non-linear and non-smooth, and the optimization routine finds multiple local minima, but cannot guarantee a global minima. However, with a number of starting "seed" matrices, an OD matrix with a good fit in terms of reproducing traffic counts can be estimated. The dominance of the mainline counts in the OD estimation and an identifiability issue is indicated from the experiments. The quality of the estimates improves as the specification error, introduced due to the discrepancy between AIMSUN and the real-world process that generates the on-ramp and off-ramp counts, reduces.
